Cheminées de Fées (France)

Cheminées de Fées (water is dripping on a mud floor. Small pebbles protect some areas of the mud from being eroded by the water).

These holes are made by water dripping down from considerable height onto a mud floor. In time, calcite may be deposited at the inside, forming negative formations.
(Hérault, France)

Negative formations that have become positive again. A negative formation is formed like this: water drops from a very high ceiling onto a sand floor and digs a deep hole in the sand. That hole is covered at the inside with a fine calcite layer. That is the negative formation. In this case, the sand floor has been washed away later on, leaving only the calcite layer of the negative formations.

How garbish can become art. This tin can was abandoned only decades ago and is now covered with flowstone.

Unique aragonite tube.
Aragonite tubes are normally formed by needles growing together. However, these tubes (1 cm diam.) are formed by rings of aragonite
